The speed to overtake the first messenger.

Answer to Problem 7P
The speed of second messenger should be
Explanation of Solution
Given information:
Speed of the first messenger is
Time taken by the first messenger when the second messenger starts is
Time taken by the second messenger to meet the first messenger after he starts is
Distance travelled by the first messenger in 1h 40min or
When the second messenger meets him is,
Let
Now the second messenger has to cover a distance of
Then his speed should be,
So, the speed of second messenger should be

They are playing a game where they randomly pick a card out of the hat four times, with replacement. Amy thinks that the probability of getting exactly two aces in four picks is equal to the probability of not getting exactly two aces in four picks. Samiha disagrees. She thinks that the probability of not getting exactly two aces is greater. The sample space of possible outcomes is listed below. A represents an ace, and K represents a king.
